    1. Bull Ridge Member of Mission Canyon Limestone —This member also does not vary greatly from equivalentbeds to the south. However, the solution zone at the baseof the member is somewhat thinner (10 to 25 feet thick),although the maximum thickness of the member (120 feet)is greater than it is in the Wyoming Province. Moreover,several thin terrigenous intervals occur above the uppersolution zone at most localities. T h e thickness of themember is quite variable (10 to 120 feet) owing to thevarying depth of post-Madison

    2. Cliffy limestone member of Mission Canyon Lime-stone— This member is essentially the same as its expression in the Wyoming Province, differing chiefly in itsslightly greater thickness. It consists of cliff-forming limestone overlying a basal solution breccia (Figure 9). Thesolution breccia (lower solution zone) is about 25 to 50

    4. the upper beds are in part shattered and brecciated likethose of the cherty dolomite member of the WyomingProvince. Stromatolites occur in some of the limestonebeds. Fossils are generally rare except for their occurrencein the lower oolitic beds, which contain a fauna of Osageanage similar to, but less diversified than, that of the underlying Woodhurst Limestone Member

    5. Lower limestone member of Mission Canyon Lime-stone— The lowest unit of the Mission Canyon Limestoneis a cherty sequence of limestone and dolomite about 280to 325 feet thick that is the time-stratigraphic equivalentof the cherty dolomite member to the south. This unitbegins with thick, commonly cross-bedded, crinoidal oos-parite strata that stand in sharp contrast to the thinnerbeds of the underlying Lodgepole Limestone. The upperpart of the member consists predominantly of interbeddedfine-grained limestone and dolomite. At some localities

    6. Woodhurst Limestone Member of Lodgepole Lime-stone — The Woodhurst in this area (Figure 8) is verysimilar to its expression in the Wyoming Province, differing by its slightly increased t e r r i g e n o u s c o n t e n t andslightly increased thickness (340 to 378 feet

    8. Identifiable fossils are rare, consisting of a fewsmall solitary corals, brachiopods, and bryozoans. Cono-donts from this unit belong to the Siphonodella crenultaZone, which is of Kinderhookian age.

      Fossils: Crinoids, solitary corals, bryozoans, brachiopods

    9. Paine Shale Member of Lodgepole Limestone — ThePaine in this area consists of about 110 to 155 feet ofpredominantly thin-bedded, dark, fine-grained, verycherty limestone (Figure 7). Most of the limestone bedsappear to be micrite or pelletal limestone, but coarsegrained bioclastic debris is also present, particularly in thelower 20 to 30 feet

    10. Cottonwood Canyon Member of Lodgepole Limestone— This member is greatly reduced from its expressionin t h e s o u t h e r n part of t h e Beartooth M o u n t a i n s . Itincludes only 2 to 3 feet of silty, dark, conodont-bearingshale and mudstone noted at three localities. It was notrecorded by Richards (1957) in the Shell Mountain section. The Cottonwood Canyon Member is slightly youngerin this province than in the Wyoming Province; its cono-dont fauna ranges from highest Siphonodella sandbergi-S.duplicata Zone to Lower Siphonodella crenulta Zone

    1. Like the cliffy limestone member it represents a periodof lagoonal and carbonate bank deposition. The terrigenous beds of the u p p e r solution zone may reflect earlypulses of the regional uplift that occurred prior to deposition of the overlying Amsden Formation

    2. T h e Bull Ridge contains a limited fauna of corals (Syr-ingopora, Diphyphyllum, Canadiphyllum?, a n dVesiculophyllum), brachiopods, and foraminifers of earlyMeramecian age

      Fossils: brachiopods, corals, foraminifers

    3. Bull Ridge Member — The highest member in theMadison Limestone consists of cliffy, medium- to thick-b e d d e d cherty limestone that overlies a t h i n - b e d d e ddolomitic siltstone and shale interval (upper solutionzone) which is brecciated at some localities. The memberis 85 to 100 feet thick in the Beartooth segment of theWyoming Province; the solution zone at its base is about30 feet thick. Like the cliffy limestone member, the limestone beds of the Bull Ridge consist of bioclastic debrisin a fine-grained matrix. Brecciation of the limestonesrelated to post-Madison karst development is a commonfeature, and red sand, silt, and clay from the overlyingAmsden cycle is present in sinkholes and solution cavities

    4. The cliffy limestone member represents a short period of evaporite deposition in a lagoonalenvironment followed by carbonate deposition on shallowoff-shore marine banks

    5. At the base of the cliff-forming unit is a solution breccia(Figure 5) about 15 to 35 feet thick that r e p r e s e n t s aleached interval of evaporites, carbonates, and terrigenoussediments (lower solution zone

      Fossils: crinoids, brachiopods, corals, foraminifers

    7. Cliffy limestone member— This member consists predominantly of cherty, medium- to thick-bedded limestoneabout 160 to 175 feet thick that forms prominent cliffsa n d flatirons t h r o u g h o u t t h e area s t u d i e d . At somelocalities many of the limestone beds are partly or completely dolomitized. The limestone consists principallyof commonly oolitic bioclastic debris

    8. The cherty dolomite member appearsto represent a restricted marine facies, perhaps lagoonalin origin. Extensive brecciation and shattering may bethe result of leaching of thin evaporite beds throughoutthe sequence. The age of the member is Osagean by virtueof its position above and below beds dated paleontologi-cally as Osagean

    13. at section 5 it consists of cherty, thinb e d d e d dolomitic limestone and dolomite (Figure 3).Megafossils are rather rare in the dolomite member; thefauna consists mainly of corals (Vesiculophyllum, Syrin-gopora, Cyathaxonia, Zaphrentites?), small brachiopods,and conodonts of Kinderhookian age (Siphonodella cre-nulta Zone). These fossils are more abundant at the morenorthern localities. The lower dolomite member appearsto represent a dolomitized shoal-water sediment that wasdeposited in clear waters that d e e p e n e d northward.

      This really is an incredible passage The whole category of nature, the body, and attitude are thrown open. Douglass is attuning us to the way that bodies and hearts and minds are composed rhetorical: that is, socially through practice. Nothing is automatic and irreversible. The province of rhetoric is being expanded here.
